Christian Proulx played his junior hockey in St. Jean, Quebec, and was drafted by the Montreal Canadiens 164th overall in the 1992 NHL Entry Draft. He returned to his junior team and promptly doubled his previous season scoring statistics. After St. Jean was eliminated in the playoffs, he joined the Canadiens farm team in Fredericton for the conclusion of the AHL season.

The intention was for Proulx to play the 1993-94 season in Fredericton, but injuries changed the Canadiens plans. In a matter of days the Canadiens lost J. J. Daigneault, Patrice Brisebois and Peter Popovic to shoulder injuries. To make matters worse, Fredericton was hardly able to help the parent club due to their own battle with the injury bug. Thus 20 year-old Christian Proulx lined up in front of goaltender Andre Racicot, who was covering for an injured Patrick Roy, on December 23, 1993 in Buffalo. The inexperienced Canadiens defensive crew fell victim to the Sabres and their new frontline goaltender, Dominik Hasek, 5-0. Proulx recorded two cross-checking penalties in the game.

Proulx recorded his first point against the Edmonton Oilers on December 29 by assisting on Brian Bellows second period goal. Three nights later his shot from the blueline got by Calgary Flames goaltender Andre Trefilov for his first NHL goal. Christian Proulx continued his aggressive play through to January 5th, when the Canadiens shutout the Nordique, 4-0, in a neutral city contest in Phoenix. At the conclusion of the Canadiens seven game road trip the team return Proulx to the American Hockey League. Jacques Demers, the Canadiens coach, indicated his impression of the defenseman when he said: " He showed the coaches and I think most of the players on this team that he can play in the NHL. I told him he would get another chance. Since his seven games in 1993-94, Proulx has plied his trade for Fredericton, San Francisco, Milwaukee and Hershey. In 1998, he moved to Europe to play in Italy and Germany
